Basic
Get started with JT Efficiency Experts — your go-to specialists for Blower Door Testing and Duct Leakage Testing.
Unlike other companies, we guarantee you’ll pass. We don’t believe in failing you just to come back and recharge like some others do. Our mission is simple: to help contractors get their final occupancy permits — fast, smooth, and stress-free.
These tests are mandatory for residential and commercial properties in Philadelphia and surrounding areas. Without a certified blower door and duct leakage test, you won’t receive your occupancy permit, and that means no closing, no move-in, and no sale.
We’re here to ensure nothing gets in your way. Our certified testing and same-day pass guarantee mean your project stays on schedule and your property stays market-ready.
Professional
Take your energy efficiency to the next level with JT Efficiency Experts — where professionalism meets results.
We offer a streamlined, no-nonsense approach to help you pass your mandatory blower door and duct leakage test — the final hurdle standing between your project and a certificate of occupancy. Don’t let this one test delay the sale or move-in of your property, especially in today’s fast-moving real estate market.
The truth is: less than 1% of new homes pass this test on the first try. That’s because most contractors and engineers are focused on structure and design — not how much air is leaking through windows, doors, and ductwork. Unfortunately, that oversight often leads to failed tests, costly delays, and unnecessary retesting.
Here’s where we’re different:
- No gimmicks. No loopholes.
- We guarantee a passing certification — same day.
- We include the essential pre-drywall checklist (required for compliance but rarely mentioned by Philadelphia Licenses & Inspections). This ensures your insulation, framing, windows, and duct systems are up to code before it’s too late.
- Most companies charge extra for this — we include it FREE with every blower door test.
We’re not here to fail your project. We’re here to get it finished — efficiently, affordably, and without delays.
Business
We offer a specialized service that’s often misunderstood as an HVAC issue — but it’s not.
Blower door and duct leakage testing require certified expertise, not just HVAC knowledge. In fact, HVAC contractors are not licensed or qualified to perform these tests unless they’ve undergone specific training, passed certification exams, and invested in the proper calibrated equipment.
At JT Efficiency Experts, we are proud to be certified air barrier test auditors, operating a smooth, systematic, and fully compliant business. We handle everything from start to finish — including uploading your certification documents directly to your Philadelphia L&I Eclipse Contractor portal, saving you time and ensuring your project stays on track.
Trust the experts who do it right the first time — no confusion, no delays.
There is no flat rate
At JT Efficiency Experts, based in Philadelphia. We don’t believe in flat rates — instead, we work with your budget and the specific needs of your project to deliver the most affordable, high-quality service possible.
"I can't say enough about the outstanding service I received from JT Efficiency Experts. Their team went above and beyond to meet our needs and exceeded our expectations with guaranteed pass certification same day!"
